13=3+10
so it is now
3+10-7
we know that 10-7=3 so we now have
3+3=6
tada
Part 1)<span>There are 100 cm in 1 m and 1000 m in 1 km. You need a curtain for a window that is 156 cm wide.
Part (a) If you wanted to convert the width to kilometers, what conversion factor should you use? Show your work.
we know that
100 cm------> 1 m
1000 m-----> 1 km
step 1
convert cm to m
156 cm---------> 156*(1/100)-----> 1.56 m
step 2
convert m to km
1.56 m------> 1.56*(1/1000)----> 0.00156 km
step 3
find the factor
156 cm---------> 156*(1/100)*(1/1000)---> 156*[1/100000]=0.00156 km
the answer part 1a) isthe conversion factor is (1/100000)Part </span><span>(b) What is the width in kilometers?
</span><span>
the answer Part 1b) is 1.56 kmPart 2)</span><span> The driver of a taxi charges $2 every minute plus a pickup fee of $3.
Part (a) Write an expression for the total cost of a taxi ride.
</span>
let
x-----> quantity of minutes of a taxi ride
y----> total cost of a taxi ride
we know that
y=2x+3
the answer Part) 2a isAn <span>
expression for the total cost of a taxi ride is </span>
y=2x+3Part <span>b) How much does an 18-min drive cost?
y=2x+3
for x=18 minutes
y=2*18+3-----> y=$39
the answer Part 2b) is$39Part 3)</span><span> Draw a net for each of the following shapes:

Can you provide more information about the problem that way I can help you as much as possible
Answer:
Every 1.71 seconds, the bacteria loses 
Step-by-step explanation:
Given

Required [Missing from the question]
Every __ seconds, the bacteria loses 
First, we model the function from t/3 to t.

Apply law of indices

Evaluate each exponent
--- This gives the number of bacteria at time t
At time 0, we have:



Let r be the time 1/2 disappears.
When 1/2 disappears, we have:



So, we have:

Substitute r for t

Substitute 

Divide both sides by 8500


Take log of both sides

Apply law of logarithm

Make r the subject



<em>Hence, it reduces by 1/2 after every 1.71 seconds</em>
A = length x width
So, this would be 4(3)
(I believe that would be it anyway …) ♀️
